IMPROVEMENT IN TOOLS FOR BENDlNG BALE-HOOKS.

Specification forming part of Letters Patent No. 170,026, dated November'16, 1875; application filed September 25, 1875.

To all whom it may concern Be it known that I, BENJAMIN R. SPRING-STEEN, of Schodack Landing, in the county of Rensselaer and State of NewYork, have invented a new and Improved Device for Bending Bale-Hooks, ofwhich the following is a specification:

In the accompanying drawing, Figure 1 represents a top view of my devicefor bending bale-hooks being in position to give the first bending tothe wire blank. Fig. 2 is a side view of my device, shown as giving thefinal bending to the hook; and Figs. 3, 4L, and 5 are top and side viewsof a wire 'balehook in different stages of construction.

Similar letters of reference indicate corresponding parts.

The object of my invention is to produce an improved device or tool formanufacturing, in rapid and convenient manner, the wire hooks used byfarmers for baling hay, straw, &c.; and the invention consists ofadevice'capable of rotation, for twisting the wire blank, and providedwith a raised shaping piece, and bending-jaws back of the same, whichare pivoted to a base-plate that is hinged to the main piece, to beswung over the raised part for imparting the final hook shape.

In the drawing, A represents the main piece or stock ofmy improveddevice or tool for bending bale-hooks, which stock is journaled into astationary box or standards, B, for being rotated by a crank at the end.The oppo' site end of stock A is provided With a raised shaping part, 0,on which the U-shaped wire blank is placed to be griped firmly at theends of the legs by a vise. Olampingjaws D are pivoted to a base-plate,E, which'is hinged to stock A by pivot-pins a, near the raised part O.The jaws D are closed by their handles, which may be locked, by anysuitable fastening device, to the hook b of stock A when in closedposition.

On closing the jaws the curved end of the close parallel running of thewire at the part acted on is produced, as shown in Figs. 1 and 3. Whenthe jaws are locked the stock is turned by the crank, which twists theends of the wire blank in front of the raised part G. The base-plate E,with itsjawsD,is then swung on the pivots a over the raised part, andthe clamped end of the wire piece bent over the forming-piece G,producing thereby the hook of the same, as shown in Figs. 4. and 5. Thejaws are then swung back, releasing the completed hook, which is thentaken out of the vise, and a new wire blank placed on the forming partand into the vise, after which the twisting and bending operations arerepeated. The baling-hooks may thus be turned out in a rapid andconvenient manner, with a regular shape, superior to those made by hand.

Having thus described my invention, I claim as new and desire to secureby Letters Patent' A device or implement for bending wire intobale-hooks, made of rotating stock, with a raised shaping-piece at oneend, and a hinged baseplate with clamping-jaws pivoted to said base, fortwisting and bending the wire into hooks of the required shape,substantially in the manner and for the purpose set forth.
